Set one of your DLE's to the dumptype. Maybe even a dummy DLE. Then run amadmin ... disklist ... command to see the relevant parameters. Change the dumptype and rerun amadmin to compare. A sample run: # amadmin DS1 disklist butch /var line 10: host butch: interface default disk /var: program "GNUTAR" exclude list "/usr/local/etc/amanda/exclude.gtar" priority 0 dumpcycle 7 maxdumps 8 maxpromoteday 10000 strategy STANDARD compress CLIENT FAST comprate 0.50 0.50 auth BSD kencrypt NO holdingdisk YES record YES index YES skip-incr NO skip-full NO -- Jon H.
